First, I'll note that plenty of people use Chrome without extensions. This issue wasn't a showstopper for any of them.

Second, you cut out the rest of the comment:

"If that causes great hardship for anyone and you want to do the work to figure out what's going on submit patches to fix it, I can provide pointers for where to start looking and code reviews for the patch."

Since that comment has anyone done anything other than updating their kernel and/or complaining? If not, why would the Chromium team think this issue was important?
